动态加载的问题
protected void Button1_Click(object sender, EventArgs e) //点击获取值
{
foreach (System.Web.UI.Control ctl in Page.Form.Controls)
{
if (ctl is CheckBox)
{
CheckBox chk = ctl as CheckBox;
if (chk.Checked == true)
{
Response.Write(chk.Text);
}
}
}
}

protected void btn_Click(object sender, EventArgs e) //点击加载
{
int j = 5;

for (int i = 1; i <= j; i++)
{
CheckBox cb = new CheckBox();
cb.Text = i.ToString();
cb.Font.Size = System.Web.UI.WebControls.FontUnit.Small;
cb.ID = "cb" + i.ToString();
cb.Checked = false;
Page.Form.Controls.Add(cb);
}
}

获取不到值，在线等

[解决办法]
他的意思是点击加载时得到5个checkbox，再选中一个或多个得到选中checkbox的值
[解决办法]

C# code

override protected void OnInit(EventArgs e){   //重新执行动态加载控件的方法}
